Product Details: Textured HDPE Geomembrane 

1. Product Overview

Our Textured HDPE Geomembrane is a high-performance anti-seepage liner engineered for demanding containment projects. Manufactured by Haoyang Environmental using 100% Virgin High-Density Polyethylene (HDPE) resin, this product is produced via advanced triple-extrusion blow molding technology.

It features a specialized textured (rough) surface—available in single-sided or double-sided configurations—designed to significantly increase interface friction. Trusted in major infrastructure and environmental projects, it delivers superior durability, chemical resistance, and slope stability.

2. Key Features & Benefits

•  Enhanced Interface Friction (Anti-Slip)

The textured surface is engineered to create a high coefficient of friction between the liner and surrounding soil or geotextiles. This prevents liner slippage on steep gradients (slopes > 1:1), making it the preferred choice for landfill final covers, reservoir banks, and tailings dams.

•  100% Virgin Material & Triple-Extrusion Process

Following Haoyang Environmental's strict manufacturing protocol, we use only pure, virgin HDPE (97.5% HDPE resin + 2.5% carbon black, anti-oxidants, and UV stabilizers). The triple-extrusion process ensures a uniform molecular structure, free from impurities found in recycled materials. This guarantees:

• High Tensile Strength: Excellent resistance to tearing and puncturing from ground settlement or sharp rocks.

• Superior Chemical Stability: Inert to a wide range of acids, alkalis, and hydrocarbons (ideal for municipal solid waste landfills, sewage treatment, and oil drilling sites).

• Optimized Flexibility: High elongation allows the liner to conform to uneven subgrades without risk of cracking.

•  Engineered for Longevity

With high carbon black content (2.0% - 3.0%) and premium UV stabilizers, our geomembranes offer exceptional resistance to environmental stress cracking and ultraviolet degradation. Designed for a service life of 50+ years (even in exposed conditions), they meet the rigorous demands of long-term containment.

•  Precise Manufacturing Standards

Produced under strict quality control systems (ISO 9001 / ISO 14001 certified), our products align with GRI-GM13, ASTM D5397, and GB/T 17643 standards. Every roll is inspected to ensure consistent thickness, density, and mechanical properties.
